Loft Conversions Thamesmead

Rooflight Conversions – Also referred to as Velux loft conversions, are the simplest and most cost-effective loft conversion designs. This method avoids altering the roof’s structure and instead incorporates roof windows, often Velux windows, into the existing roof slope. They afford natural light, ventilation, and aesthetics.

Dormer Loft Conversions – Transform the attic space by extending the existing roof upwards to create more height. The design typically entails constructing a flat-roofed, box-shaped extension projecting from the roof slope. Pitched and hipped roofs also get incorporated into the design based on space availability. Dormer conversions offer more usable space compared to roof light conversions and allow for the integration of dormer windows to introduce natural light. Rear dormers are relatively more popular.

Hip-to-Gable Loft Conversions – Free up space restricted by a hipped roof, often a feature of 1930s semi-detached homes and end-of-terrace properties. They convert the sloping end of the roof (hip) to a vertical wall (gable), creating more headroom and floor space. Detached properties with a hipped roof on either side can have a double hip-to-gable conversion to maximise space.

Mansard Loft Conversions – Marked by substantial structural alterations to the roof, these conversions create an almost vertical wall. A new horizontal roof meets the sides of the wall in a steep pitch. Windows get housed in small dormers. Mansard conversions provide substantial space to accommodate multiple rooms, rendering them popular, particularly in urban settings. A double mansard offers the seamless appearance of a separate storey.

L-shaped Loft Conversions – formed with two interconnected dormers sitting right-angled to each other, they can add twice the space. These are popular in Victorian properties with an existing rear wing. Typically, one dormer is positioned on the outrigger, while the other sits on the primary roof. You can even create an L-shaped with a balcony for a roof terrace space.

Loft conversion cost has several deciding factors, including the size, design, and materials. More complex design features can increase costs as well as aesthetic appeal. The average loft conversion costs for each type are as follows;

Room in the roof conversion (basic) –  £35,000

Dormer loft extension – £50,000

Mansard extension – £60,000 – £65,000

Hip-to-gable extension – £65,000

L-shaped extension – £65,000 – £75,000

A loft extension isn’t just about adding extra space but about building living spaces that enhance functionality, aesthetics, and value. A key reason to have loft conversion companies undertake your project is to ensure your new addition adheres to the numerous building regulations and planning guidelines. It is a tricky landscape to navigate as a non-professional. Any construction that does not fall within permitted development rights or does not have planning permission can get pulled down, along with hefty fines. 

Safety is a vital part of a building. A structural engineer’s expertise is necessary to make accurate assessments and calculations that guarantee structural integrity. From drawing up plans to preparing method statements, a loft conversion is a job for a professional team with a good track record. Hiring one can save you a mountain of worry and work.
